It appears the there is not enough gas from the 6.5 loads to cycle the buffer/spring that is set up for the 223 gas/barrel length, and possibly the gas port size is too small. Other things to consider trying are changing the buffer weight/spring lighter to see if will cycle, or using a powder/load combo that produces more gas.
Have several larger bore AR's, and if practical prefer to use reduced gas volume rather heavier buffer/spring, so long as the combo is reliable. Overly large gas ports was common problem when more manufacturers started making larger bore ar's, which may be why adj gas blocks became so popular.
